JOHN X. BROWNE, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF OF HIS RIGHTTO CHARLES H. QUAIL, OF SAME PLACE.

lNKlNG-FOUNTAIN FOR PRINTING-MACHINES..

SPECIFICATION formfng' part of Letters Patent No. 229,303, dated June29, 1880.

' Application filed October 14, 1879.

To all whom it may concern:

Be it known that I, JOHN X. BROWNE, (assignor of one-half interest toCHARLES H.

' QUAIL,) of Brooklyn, Kings county, New York,

have invented, made, and applied to use Improvements in the Constructionof Fountains for Printing-Presses; and I do hereby declare that thefollowing is a full, clear, and correct description of the same,reference being had to the accompanying drawings, making part of thisspecification, and to the letters of reference marked thereon,.in which-Figure 1 is a top view of my improved fountain. Fig. 2 is a view of thesame, the knife being removed. Fig. 3 is a rear view of the fountain.Fig. at is a view of the under side of the knife. Fig. 5 is a transversesection of the fountain.

In the drawings like parts of the invention are indicated by the sameletters of reference.

The nature of the present invention relates to improvements in theconstruction of fountains for printing-presses, as more fullyhereinafter set forth, and will be found to relate 2 5 to the class offountains more frequently employed in job-printing presses.

To enable those skilled in the arts to make and use my invention, I willdescribe its construction and operation.

A shows the trough or lower portion of the fountain, in the frontportion of which is inserted the duct-roller B, free to revolve in theboxes 0, attached at each end of the trough A.

The interior of the trough A is provided 3 5 with the inclined ribs a,and about centrally with a rod, b, around which is wound the wire 0,terminating in an eye or loop, d.

D shows the knife of the fountain, provided upon its under side with therib or projecting o strip 0, and to this rib or projecting strip 6 isattached the tongue f. V

Back of the knife D projects, about cen trally, a plate, h, providedwith a slot, through which passes a hook-bolt, t, over the upper end of5 which is passed a thumb-screw, is.

At the rear outer side of the trough A, about centrally, is placed apin, 1, with which, when the knife D-is placed in position in the troughA, the hook of the bolt 1' engages.

The knife D, when placed within the trough A, has the rib or projectingstrip 0 supported upon the inclined ribs a, upon which, as the positionof the knife D relatively to the ductroller B is changed, it may be saidto rock, and in this position the tongue f is received within the eye orloop (Z.

The book of the bolt i engages with the pin I, placed in the rear outerside of the trough A.

Such being the construction,the operation will be readilyunderstood.

The knife is placed within the trough or. lower portion of the fountain,as already described, and the ink to be supplied to the ductroller isplaced upon the knife, which occupies the inclined position clearlyshown in Fig. 5 of'the drawings, by which the flow of the ink isfacilitated; and by turning the thumb-screw k upon the upper portion ofthe hoolcbolt the position of the knife relatively to the ductroller maybe varied. If the screw be depressed, the lower edge of the knife isbrought nearer the duct-roller, and a less quantity of ink will be takenup by the ductroller in its revolution than if the screw be elevated (soto speak) and the lower or forward edge of the 7 5 knife be brought awayfrom the duct-roller, the knife, as previously stated, having a rockingmotion imparted to it by screwing or unscrewing the thumb-screw Ia.

A fountain thus constructed can be easily 8o taken apart forcleaning,and will befound economical in the use of inks for printing purposes.

Having now set forth my invention, what I claim as new is 8 Thecombination, with a trough, A, ribbed, as at a, and provided with a loopor eye, d, of the knife D, having upon its under side the rib orprojecting strip 6 and tongue f, the slotted plate h, hook-bolt i,thumb-screw k, and pin l, constructed and operating substantially as andfor the purposes set forth.

JOHN X. BROWNE.
